Question

Difference between diamond and graphite

Answer 1

Both Diamond and Graphite are a crystalline form of carbon (Both are made of pure carbon). However they are the same in the chemical composition, they differ a lot in the physical composition. On the Moh’s scale, Diamond ranks as 10 making it the hardest mineral as compared to Graphite, which is the softest. Thus, based on the physical properties, they are used for different purposes.

Answer 2

Hey !!

DIAMOND

• Diamond is very hard.
• It has high density.
• It is a bad conductor of electricity but good conductor of heat than graphite.
• It possesses three dimensional net work structure.
• Chemical reactivity is low.
• Carbon undergoes sp³ hybridisation.
• C--C bond length is 154 pm.

GRAPHITE

• Graphite is soft.
• It has relatively low density.
• It is good conductor of heat and electricity.
• It possesses a sheet type structure.
• Chemical reactivity is high.
• Carbon undergoes sp² hybridisation.
• C--C bond length 142 pm.

GOOD LUCK !!
